Abstract
Aiming at the existing problems in the current network infrastructure,which have complex design,limited port expansion and high maintenance costs. This paper proposes a longitudinal heterogeneous technology scheme based on Intelligent Resilient Framework( IRF) virtualization technology. This scheme virtualizes several low-end switches and IRF system into a single logical device. On one hand,the numbers of ports of the logic device are increased,meanwhile it is sampler to manage for big switching network. On the other hand,the scheme reduces the cost of building big switching network. In the plane of network topology,multiple longitudinal links between low-end switch and IRF system are bound to a logic link by LACP technology,and the traffic can be balanced sharing among them. In the plane of protocol control, the system control and management pane of the low-end switch is shifted up,and it is centrally controlled and decided by IRF system. Finally,the paper analyzes the reliability,traffic load balancing,expansion and maintenance with the existing schemes. Experimental results show the scheme can solve the shortcomings of the existing schemes,and enhance the port density with lower costs.关键词
